Description

Technical Field

[0001] This application relates to the technical field of human wearable devices, and particularly to an elastic carrying device and an elastic backpack. Background Art

[0002] As a carrying method that has been used by humans for thousands of years, backpacks have unique advantages, such as freeing the hands and being stable and reliable. Therefore, backpacks have become one of the preferred solutions for humans to carry personal items today. Soldiers usually need to carry a large load and march for a long time. When walking with a load on the back, the lower limb muscles of the human body will do extra work, which will cause fatigue of the lower limb muscles and make it impossible to walk with a load for a long time. Moreover, the shoulder straps of most backpacks are basically fixed on the back of the backpack. Therefore, when the center of gravity vibrates up and down during walking, the pressure of the backpack on the shoulders is very large, resulting in soreness of the shoulder muscles, which will increase the fatigue of the human body.

[0003] Precisely because of this, elastic backpacks with a buffering function have emerged. Existing elastic backpacks separate the backpack from the human back, allowing the backpack to vibrate up and down to basically maintain the same horizontal height during walking, which can effectively reduce problems such as muscle soreness and increase the load-bearing distance.

[0004] However, although existing elastic backpacks can reduce the energy loss of the human body, their integral structure makes loading and unloading very difficult, and the loading and unloading speed is slow, making them very inconvenient to use. For soldiers, this may result in wasting precious time during battles. Summary of the Invention

[0005] This application provides an elastic carrying device and an elastic backpack, which have a modular structure, are very convenient and efficient for loading and unloading the backpack, and can save the precious wartime time of soldiers.

[0006] In a first aspect, an elastic carrying device is provided, including: a back plate for being worn and supported on the back of the human body; a connecting plate detachably mounted on the back plate; a backpack mounting plate for fixedly mounting a backpack, the backpack mounting plate being movably mounted on the connecting plate through a linear slide rail assembly and a buffer assembly, the linear slide rail assembly being used to guide the backpack mounting plate to move up and down relative to the connecting plate, and the buffer assembly being used to reduce the vibration amplitude of the backpack mounting plate in the vertical direction.

[0007] According to the elastic carrying device provided by the embodiments of this application, through modular design, the connecting plate is detachably mounted on the back plate, the connecting plate is connected to the backpack mounting plate, and a backpack is mounted on the backpack mounting plate, making it very convenient and efficient to load and unload the backpack, being able to save the precious wartime time of soldiers and facilitating soldiers to quickly enter the battle.

[0008] In addition, the backpack mounting plate is movably mounted on the connecting plate through a linear slide rail assembly and a buffer assembly. During the process of a person walking with a backpack load, the linear slide rail assembly guides the backpack to reciprocate in the vertical direction, and the buffer assembly reduces the vibration amplitude generated by the up-and-down reciprocating movement of the backpack, so that the impact force on the human shoulder by the combat vest is well buffered, the pressure on the shoulder by the backpack is reduced, fatigue damage to the shoulder muscles caused by the backpack is avoided, and the peak value of the ground pushing force of the lower limbs is reduced.

[0009] In a possible design, the connecting plate is detachably mounted on the back plate through a plurality of sets of snap components.

[0010] In a possible design, each set of the snap components includes a female snap and a male snap that are used in plug-in cooperation; the female snap is mounted on one of the back plate and the connecting plate, and the male snap is mounted on the other of the back plate and the connecting plate; the female snap includes a latch for locking the male snap, and the latch is connected to a pull rope. By pulling the pull rope, the latch is pulled to release the locking of the male snap.

[0011] According to the elastic load-bearing device provided by the embodiment of the present application, when a soldier needs to carry a backpack, the soldier can first easily put on the combat vest and fix the backpack on the backpack mounting plate. Then, another companion inserts the male snap into the female snap correspondingly. After the male snap is inserted into the female snap, the latch can lock the male snap to prevent the connecting plate from falling off during walking. The end of the latch is connected to a pull rope. When the backpack needs to be removed, the user can pull the latch backward through the pull rope to release the locking of the male snap, so that the connecting plate can be removed from the back plate, thereby facilitating the soldier to remove the backpack.

[0012] In a possible design, the male snap includes a male snap seat, a connecting column vertically arranged on the male snap seat, and a male snap head connected to the front end of the connecting column. The diameter of the male snap head is larger than the diameter of the connecting column to form a clamping groove between the male snap head and the male snap seat; the female snap includes a female snap body, and a jack for inserting the male snap head is formed on the female snap body. When the male snap head is inserted into the jack, the latch is elastically clamped in the clamping groove to lock the male snap.

[0013] In a possible design, a slot perpendicular to the jack is formed in the female snap body, and the latch is movably arranged in the slot through a spring; a semicircular notch is formed at the front end of the latch. When the male snap head is inserted into the jack, the male snap head squeezes and passes through the semicircular notch, and under the action of the spring, the semicircular notch abuts against and surrounds the connecting column; the rear end of the latch is connected to the pull rope.

[0014] In a possible design, the latch block has a rectangular frame structure, a stop bar fixedly connected to the female buckle body is arranged inside the rectangular frame structure, and the spring is arranged between the front end of the rectangular frame structure and the stop bar.

[0015] Through the above settings, the latch block can be accurately positioned, a reliable elastic connection between the latch block and the female buckle body can be achieved, and the connection between the rear end of the stop bar and the pull rope can be facilitated. Furthermore, a reliable and efficient detachable connection between the back plate and the connecting plate can be realized, which is convenient for the installation and unloading of the backpack and facilitates the soldiers to quickly enter the battle.

[0016] In a possible design, one end of the pull rope is connected to the multiple latch blocks corresponding to the multiple snap components, and the other end is connected to a handle.

[0017] In a possible design, the buffer assembly includes multiple fixed pulleys, an elastic rope in a loop shape and wound around the multiple fixed pulleys, and at least one movable pulley suspended on the elastic rope; the multiple fixed pulleys are rotatably arranged on the connecting plate, and the at least one movable pulley is rotatably arranged on the backpack mounting plate.

[0018] In a possible design, at least one of the fixed pulleys is adjustably mounted on the connecting plate to change the pre-tightening force of the elastic rope.

[0019] Through the above settings, on the one hand, the initial pre-tightening force of the elastic rope can be flexibly adjusted according to the weight of the backpack, so that the backpack is always suspended at a suitable height. On the other hand, it is also convenient to remove and replace the elastic rope. Elastic ropes with different elastic forces can be installed according to the weight of the backpack to meet the usage requirements of different load weights and make the buffering effect better.

[0020] In a possible design, the movable pulley is adjustably mounted on the backpack mounting plate in terms of height.

[0033] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "side", "front", "rear", etc. is based on the installed orientation or positional relationship, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0034] It should also be noted that in the embodiments of the present application, the same reference numerals are used to represent the same components or the same parts. For the same parts in the embodiments of the present application, only one of the parts or components may be marked with a reference numeral in the figure. It should be understood that the reference numerals are equally applicable to other identical parts or components.

[0035] The embodiments of the present application provide an elastic carrying device and an elastic backpack, which have a modular structure. The loading and unloading of the backpack are very convenient and efficient, and can save the precious wartime time of soldiers.

[0036] The embodiments of the present application first provide an elastic carrying device. Figure 1 It is a schematic structural diagram of the elastic carrying device provided by the embodiments of the present application. Figure 2 It is a schematic structural diagram of the wearing part of the elastic carrying device provided by the embodiments of the present application. Figure 3 It is a schematic structural diagram of the detachable part of the elastic carrying device provided by the embodiments of the present application.

[0037] As Figures 1-3 shown, the elastic carrying device provided by the embodiments of the present application is used to carry heavy objects such as backpacks on the human body. The elastic carrying device includes a back plate 2, a connecting plate 3, and a backpack mounting plate 4. Among them,

[0038] The back plate 2 is for wearing and is supported on the back of the human body. In the embodiments of the present application, the elastic carrying device further includes a combat vest 1. The back plate 2 is fixed on the combat vest 1 and is worn and supported on the back of the human body through the combat vest 1. Optionally, in other embodiments, the back plate 2 can also be worn on the back of the human body by other means such as shoulder straps and waist belts, and the present application does not limit this.

[0039] The connecting plate 3 is detachably mounted on the back plate 2 through a plurality of snap components.

[0040] The backpack mounting plate 4 is used to fixedly mount the backpack. The backpack mounting plate 4 is movably mounted on the connecting plate 3 through a linear slide rail assembly and a buffer assembly. The linear slide rail assembly is used to guide the backpack mounting plate 4 to move up and down relative to the connecting plate 3, and the buffer assembly is used to reduce the vibration amplitude of the backpack mounting plate 4 in the vertical direction.

[0041] According to the elastic backpack device provided by the embodiments of the present application, through modular design, the connecting plate 3 is detachably mounted on the back plate 2 through multiple sets of buckle components. The connecting plate 3 is connected to the backpack mounting plate 4, and a backpack is mounted on the backpack mounting plate 4, making the loading and unloading of the backpack very convenient and efficient, saving the precious wartime time of soldiers and facilitating soldiers to quickly enter the battle.

[0042] In addition, the backpack mounting plate 4 is movably mounted on the connecting plate 3 through a linear slide rail component and a buffer component. During the process of a person walking with a backpack load, the linear slide rail component guides the backpack to make a reciprocating motion in the vertical direction, and the buffer component reduces the vibration amplitude generated by the up and down reciprocating motion of the backpack, so that the impact force of the combat vest 1 on the human shoulder is well buffered, reducing the pressure of the backpack on the shoulder, avoiding fatigue damage to the shoulder muscles caused by the backpack, and reducing the peak value of the ground pushing force of the lower limbs.

[0043] In the embodiments of the present application, the connecting plate 3 is detachably mounted on the back plate 2 through multiple sets of buckle components. For example Figure 2 in the 4 sets shown in the figure, the 4 sets of buckle components are respectively arranged at the 4 corners of the rectangular back plate 2, so as to reliably mount the connecting plate 3 on the back plate 2. In other embodiments, the connection between the two can also be achieved through more or fewer sets (such as 3 or 6 sets) of buckle components, and the present application does not limit this.

[0044] The buckle component provided by the embodiments of the present application includes a female buckle 6 and a male buckle 7 that are inserted and cooperated with each other. The following further introduces the buckle component provided by the embodiments of the present application with reference to the drawings. Figure 4 is an exploded view of the female buckle 6 provided by the embodiments of the present application. Figure 5 is a perspective view of the female buckle 6 provided by the embodiments of the present application. Figure 6 is a structural schematic diagram of the male buckle 7 provided by the embodiments of the present application.

[0045] As Figures 2-6 shown, in the embodiments of the present application, the female buckle 6 is mounted on the back plate 2, and the male buckle 7 is mounted on the connecting plate 3. The female buckle 6 includes a locking block 63 for locking the male buckle 7. The locking block 63 is connected to a pull rope 8, and the locking block 63 is pulled by the pull rope 8 to release the locking of the male buckle 7.

[0046] Specifically, as Figure 4 shown, multiple female buckle mounting holes 65 (such as two in the figure) are opened on the female buckle 6, and multiple female buckle mounting screws 65a respectively pass through the female buckle mounting holes 65 and are tightly connected to the back plate 2, so as to mount multiple female buckles 6 on the back plate 2.

[0047] Similarly, a plurality of male buckle mounting holes 74 are formed in the male buckle 7 (for example, one on each of the left and right in the figure). The male buckle mounting screws are correspondingly inserted into the male buckle mounting holes 74 and fixedly connected to the connecting plate 3, so as to mount the plurality of male buckles 7 on the connecting plate 3. The plurality of female buckles 6 and the plurality of male buckles 7 are arranged in one-to-one correspondence, enabling the insertion and cooperation of the two, and further enabling the detachable connection between the back plate 2 and the connecting plate 3.

[0048] According to the elastic carrying device provided by the embodiment of the present application, when a soldier needs to carry a backpack, the soldier can first easily put on the combat vest 1 and fix the backpack on the backpack mounting plate 4. Then, another companion inserts the male buckle 7 into the female buckle 6 correspondingly. After the male buckle 7 is inserted into the female buckle 6, the locking block 63 can lock the male buckle 7 to prevent the connecting plate 3 from falling off during walking. A pull rope 8 is connected to the end of the locking block 63. When the user needs to remove the backpack, the user can pull the locking block 63 backward through the pull rope 8 to release the locking of the male buckle 7, so that the connecting plate 3 can be removed from the back plate 2, thus facilitating the soldier to remove the backpack.

[0049] As Figure 2 shown, one end of the pull rope 8 is connected to a plurality of (for example, Figure 2 4 in the figure) locking blocks 63 corresponding to the plurality of snap-fastener assemblies, and the other end is connected to a handle 9. Through the above settings, it is convenient for the user to pull a plurality of locking blocks 63 simultaneously, and thus the efficiency of backpack disassembly can be improved.

[0050] Optionally, in other embodiments, the positions of the two can also be swapped, with the male buckle 7 mounted on the back plate 2 and the female buckle 6 mounted on the connecting plate 3, and the detachable connection between the back plate 2 and the connecting plate 3 can also be achieved.

[0051] As Figures 2-6 shown, the male buckle 7 includes a male buckle seat 71, a connecting column 72 vertically arranged on the male buckle seat 71, and a male buckle head 73 connected to the front end of the connecting column 72. The diameter of the male buckle head 73 is larger than that of the connecting column 72 to form a clamping groove between the male buckle head 73 and the male buckle seat 71, so as to facilitate the locking block 63 to be clamped into the male buckle 7 for locking operation.

[0052] The female buckle 6 includes a female buckle body 61. A jack 62 for inserting the male buckle head 73 is formed on the female buckle body 61. When the male buckle head 73 is inserted into the jack 62, the locking block 63 is elastically clamped in the clamping groove to lock the male buckle 7.

[0053] Further, a slot 64 perpendicular to the jack 62 is formed in the female buckle body 61. The locking block 63 is movably arranged in the slot 64 through a spring 68. When the male buckle head 73 is not inserted, the front end of the locking block 63 extends into the jack 62.

[0054] A semi-circular notch 63a is formed at the front end of the clamping block 63. When the male buckle head 73 is inserted into the jack 62, the male buckle head 73 squeezes through and passes through the semi-circular notch 63a, and the clamping block 63 is squeezed and moves backward. When the male buckle head 73 is completely inserted, under the action of the spring 68, the semi-circular notch 63a is inserted into the clamping groove and abuts against and surrounds the connecting column 72. At this time, since the side wall of the clamping block 63 abuts against the rear end face of the male buckle head 73, the male buckle 7 is locked and cannot be removed from the female buckle 6.

[0055] Optionally, in order to facilitate the insertion and mating, a transition chamfer can be provided at the front end of the male buckle head 73.

[0056] Optionally, in order to facilitate the insertion and mating, a transition chamfer can also be provided at the front end of the clamping block 63.

[0057] Optionally, in order to facilitate the insertion and mating, the jack 62 can be a tapered hole.

[0058] The rear end of the clamping block 63 is connected to the pull cord 8. When the pull cord 8 is pulled, the clamping block 63 moves backward and exits from the clamping groove, thereby being able to release the locking of the male buckle 7.

[0059] As Figure 4 、 5 shown, the clamping block 63 has a rectangular frame structure. A retaining bar 66 fixedly connected to the female buckle body 61 is arranged inside the rectangular frame structure, and the spring 68 is arranged between the front end of the rectangular frame structure and the retaining bar 66.

[0060] That is to say, the clamping block 63, the retaining bar 66, and the spring 68 are all arranged in the slot 64, and the retaining bar 66 and the spring 68 are located inside the clamping block 63. The retaining bar 66 is further fixedly connected to the female buckle body 61, and the spring 68 is elastically arranged between the clamping block 63 and the retaining bar 66. Through the above settings, the clamping block 63 can be accurately positioned, a reliable elastic connection between the clamping block 63 and the female buckle body 61 can be achieved, and the connection between the rear end of the clamping block 63 and the pull cord 8 can be realized. Furthermore, a reliable and efficient detachable connection between the back plate 2 and the connecting plate 3 can be achieved, facilitating the installation and uninstallation of the backpack and enabling the soldier to quickly engage in combat.

[0061] As Figure 5 、 6 shown, a retaining bar mounting hole 67 is also formed on the female buckle body 61, and a retaining bar mounting screw 67a is inserted into the retaining bar mounting hole 67 to fix the retaining bar 66 to the female buckle body 61.

[0062] As Figure 3 、 7 shown, in order to reduce the weight of the connecting plate 3, a plurality of hollow portions 32 are further formed inside the connecting plate 3. For example, the shape of the hollow portion can be rectangular, and the plurality of hollow portions 32 are arranged side by side and at equal intervals on the left and right sides of the connecting plate 3.

[0063] As Figure 1 、 3 shown, a strap 5 is provided on the outer side of the backpack mounting plate 4 to facilitate the fixed installation of the backpack. The strap 5 may include a plurality of vertical straps and horizontal straps to achieve reliable installation and fixation of the backpack.

[0064] In the embodiment of the present application, the backpack mounting plate 4 is movably mounted on the connecting plate 3 through a linear slide rail assembly and a buffer assembly to achieve elastic connection between the two. The slide rail assembly and the buffer assembly will be further introduced below with reference to the accompanying drawings.

[0065] As Figure 7 、 8 shown, in the embodiment of the present application, the linear slide rail assembly includes a sliding groove 10 and a guide rail 11 that are slidably engaged, and the guide rail 11 is slidably disposed in the sliding groove 10. The linear slide rail assembly includes a total of two groups, which are correspondingly disposed on the left and right sides of the connecting plate 3. The sliding groove 10 is fixedly disposed on the connecting plate 3, and the guide rail 11 is correspondingly disposed on the backpack mounting plate. The guide rail 11 can slide up and down in the sliding groove 10, thereby guiding the backpack mounting plate 4 to move up and down relative to the connecting plate 3 and preventing movement in other directions.

[0066] Optionally, in other embodiments, the linear slide rail assembly may also include more (for example, 3) or fewer (for example, 1) groups, and the present application does not limit this.

[0067] Optionally, in other embodiments, the positions of the sliding groove 10 and the guide rail 11 can be swapped. The sliding groove 10 can be disposed on the backpack mounting plate 4, and the guide rail 11 can be disposed on the connecting plate 3, and the above-mentioned sliding orientation effect can also be achieved.

[0068] As Figure 7 、 8 shown, the buffer assembly includes a plurality of fixed pulleys 12 (5 in this embodiment), an elastic rope 13 in an annular shape and wound around the plurality of fixed pulleys 12, and at least one movable pulley 14 (2 in this embodiment) suspended on the elastic rope 13; the plurality of fixed pulleys 12 are rotatably disposed on the connecting plate 3, and at least one movable pulley 14 is rotatably disposed on the backpack mounting plate 4.

[0069] In the present application, the "fixed" in "fixed pulley" and the "movable" in "movable pulley" are both relative to the connecting plate 3. The fixed pulley 12 is rotatably disposed on the connecting plate 3 and cannot be displaced relative to the connecting plate 3, so it is called a "fixed pulley". The movable pulley 14 is rotatably disposed on the backpack mounting plate 4 and is further suspended (hooked) on the elastic rope 13 and can be displaced relative to the connecting plate 3 to achieve an elastic buffering effect, so it is called a "movable pulley".

[0070] In the embodiment of the present application, the elastic rope 13 in the shape of an annular belt is wound around the outer periphery of a plurality of fixed pulleys 12 and can rotate. When the movable pulley 14 moves up and down, the elastic force on the elastic rope 13 is evenly distributed to each part of the elastic rope 13. While improving the elastic buffering effect, the service life of the elastic rope 13 can be increased.

[0071] When the backpack moves up and down in the vertical direction, the elastic rope 13 will be stretched, and part of the impulse generated instantaneously is offset by the elastic rope 13, playing a good buffering role, reducing the amplitude of the reciprocating motion of the backpack in the vertical direction, greatly reducing the instantaneous impulse of the backpack borne by the human shoulder, avoiding strong impact force on the human shoulder by the combat vest 1, and improving the comfort of the backpack.

[0072] Further, as Figure 7 shown, at least one fixed pulley 12 is adjustably installed on the connecting plate 3 to change the initial pre-tightening force of the elastic rope 13. Different load weights are required in different situations. Through the above settings, on the one hand, the initial pre-tightening force of the elastic rope 13 can be flexibly adjusted according to the weight of the backpack, so that the backpack is always suspended at a suitable height. On the other hand, it is also convenient to remove and replace the elastic rope 13. Elastic ropes 13 with different elastic forces can be installed according to the weight of the backpack to meet the usage requirements of different load weights and make the buffering effect better.

[0073] As Figure 7 shown, in the embodiment of the present application, a total of 5 fixed pulleys 12 are provided, and more fixed pulley mounting holes 31 can be provided on the connecting plate 3 to facilitate the adjustment of the installation position of the fixed pulley 12. For example, a plurality of fixed pulley mounting holes 31 are arranged at intervals on the center line of the connecting plate 3. At this time, the lowermost fixed pulley 12 can be installed at a position higher or lower relative to the current installation position according to requirements, and thus the initial pre-tightening force of the elastic rope 13 can be adjusted.

[0074] As Figure 8 shown, the movable pulley 14 is adjustably installed on the backpack mounting plate 4. Through the above settings, the suspension height of the backpack can be controlled within a suitable range by adjusting the installation height of the movable pulley 14. Specifically, a plurality of groups of movable pulley mounting holes 41 are arranged at intervals along the height direction of the backpack mounting plate 4, and the two movable pulleys 14 can be installed at suitable positions according to requirements.

[0075] In a second aspect, the embodiment of the present application further provides an elastic backpack, including a backpack body and the elastic carrying device provided in any one of the foregoing embodiments for carrying the backpack body on a human body.

[0076] Since the elastic backpack adopts the elastic load-bearing device provided by the above-mentioned embodiment, the elastic backpack also has the corresponding technical effects of the elastic load-bearing device, which will not be elaborated here.

[0077] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
